In order to improve the ventilation pipe processing technology, manufacturers need to constantly face different types and different quality products. It is of great benefit to us to improve the processing technology of our products. Only by constantly improving the overall processing technology, can we have better quality assurance, which is the guarantee of better use of our products in the future. You should really pay attention to this, after all, it really matters to our future use.

通風管道系統的工作噪聲一般來源于：風管的振動，具體表現在以下幾個方面。由于風管數據為鍍鋅板或金屬材料，施工時應嚴格按照施工驗收規范選擇鋼板厚度和施工工藝，如風管制造誤差、平直度、風管加固、支吊架選擇和制造設備等。在施工階段，出風口不應盡可能靠近設備。電風扇的前后長度應盡可能超過5米。

The working noise of ventilation duct system generally comes from the vibration of air duct, which is shown in the following aspects. Since the data of air duct is galvanized sheet or metal material, the steel plate thickness and construction technology should be selected strictly according to the construction acceptance specification, such as air duct manufacturing error, straightness, duct reinforcement, support and hanger selection and manufacturing equipment. In the construction stage, the air outlet should not be as close to the equipment as possible. The front and rear length of the electric fan should be more than 5 meters as far as possible.

通風管道加工以下是一些經驗。

The following are some experiences in the processing of ventilation ducts.

1.螺旋風管的拐角應小化。

1. The corner of spiral duct should be minimized.

2、軟接頭設備規范，防止軟帆布松發式阻力和風噪。

2. Soft joint equipment specification, to prevent soft canvas loose resistance and wind noise.

3.螺旋風管風機葉輪系統動平衡調整合理正常，正負波動不超過5線。

3. The dynamic balance adjustment of the impeller system of spiral duct fan is reasonable and normal, and the positive and negative fluctuation is not more than 5 lines.

4、控制出風口和回風區間，防止空氣對流自激現象和小流通空間。

4. Control the air outlet and return air area to prevent air convection self excitation phenomenon and small circulation space.

5.懸架應配備一個彈簧懸架的全職連接器，以減少工作期間由扭轉引起的跳動或公共頻率。

5. The suspension shall be equipped with a full-time connector of spring suspension to reduce runout or common frequency caused by torsion during operation.

通風管道連接原理：

Ventilation pipe connection principle:

以焊接為主要連接方式的管道，應設置足夠數量的法蘭連接;以螺紋為主要連接方式的連接管道，應設置足夠數量的活接頭。

For pipes with welding as the main connection mode, sufficient flange connection shall be set; for connecting pipes with thread as main connection mode, sufficient number of movable joints shall be set.

通風管道安裝及處理系統的支撐原則：管道不應直接支撐在有閥門部件的設備上，應單獨設置支架或吊架。管道焊縫位置應在施工方便或受力較小的地方，焊縫不應位于支架處，距離不應小于200 mm

The support principle of ventilation pipe installation and treatment system: the pipe should not be directly supported on the equipment with valve components, but should be separately set with support or hanger. The position of pipe weld should be in the place where construction is convenient or the stress is small. The welding seam should not be located at the support, and the distance should not be less than 200 mm

Processing of ventilation pipe in Shandong Province

通風管道加工面對不同的含塵氣體有不同的性質，所以凈化的分段處理應該不同。在通風管道處理系統的布局中，一定確保整個系統的泄漏量很小，并且在吸塵口有足夠的空氣量。通風管道處理系統的布置應減少阻力。圓形風管強度大，材料消耗少，但加工工藝復雜，占用空間大。不銹鋼風管易于布置和加工，應用廣泛。

There are different properties of different dust containing gases in the ventilation duct processing, so the segmented treatment of purification should be different. In the layout of the ventilation duct treatment system, make sure that the leakage of the whole system is small and there is enough air at the dust suction port. The arrangement of ventilation duct treatment system should reduce resistance. Circular air duct has high strength and less material consumption, but its processing technology is complex and takes up a lot of space. Stainless steel air duct is easy to arrange and process, so it is widely used.
